Let's look at some history and context and, then, I'll tell you what I think is really behind the push this time, supported by some data. No punishment has ever possessed enough power of deterrence to prevent the commission of crimes. On the contrary, whatever the punishment, once a specific crime has appeared for the first time, its reappearance is more likely than its initial emergence could ever have been. Hannah Arendt (1906-75), German-born U.S. political philosopher.
